Description

Rockfall Protection {A fence for prevent stone from falling off to the road}

The present invention relates to a rockfall prevention measures, in particular, it is possible to install a barrier plate while reinforcing the frame of the barriers without compromising the structural strength of the rockfall prevention barrier frame, and to separate and recombine the barrier plate to remove the spilled soil or rockfall. It is intended to be simple and quick.

Conventional technology related to the present invention is known as "preventive measures of falling rocks and sato down the mountain road" of the Korean Utility Model Registration Application No. 98-9894, which is shown in Figure 1, attached to the ground at predetermined intervals In constructing the falling rock and sand fall prevention measures to install the wire mesh 200 in the installed frame 100, the wire mesh 200 is installed on the frame 100 to a predetermined height from the ground, the wire mesh 200 is installed After forming a plurality of fastening holes 101 at the bottom of the non-frame 100, the blocking plate 300 having the long holes 301 formed on all sides corresponding to the fastening holes 101 is bolted to the frame 400. It was fastened to be detached from the bottom of the 100).

On the other hand, such a conventional rockfall prevention measures had to puncture the fastening hole 101 for the installation of the blocking plate 300 in the lower portion of the frame 100, the structural strength of the frame 100 supporting the rockfall prevention measures Not only was there a problem in that the vulnerable, but the blocking plate 300 is composed of a structure that is coupled to and separated from the frame of the graffiti prevention measures by bolts and nuts, so the work was cumbersome because the bolts had to be released and tightened when dismantling and recombining. There was a problem such as a delay in working time, the entire blocking plate was made of a curved iron plate to hurt the aesthetics of the roadside and obstruct the driver and passenger's vision.

The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to install a detachable blocking plate at the bottom of a rockfall prevention barrier, and to weaken the structural strength of the barrier by drilling a fastening hole in a conventional frame. It is possible to escape from the previous method, and to facilitate the separation and recombination of the blocking plate conveniently and quickly, and the blocking plate itself is in harmony with the fall prevention measures to improve the aesthetics of the roadside.

In order to achieve the above object, the present invention attaches the brackets to the upper and lower edges of both ends of the blocking plate by welding on the lower front inside of the frame of the rockfall prevention measure, and the four edges of the front side of the blocking plate are caught by the bracket. The tennis ball is installed in a rotatable manner, and the bracket attached to the frame has a ruler hook portion formed at the front thereof, and a support portion supporting the rear surface of the block plate is formed at the rear thereof, and the ruler ball is known from the front of the block plate. It provides a rockfall prevention plan that can be easily rotated by using a tool to secure the bracket.

The present invention is to select the barrier plate in accordance with the surrounding landscape by making it possible to manufacture by selecting the ridge mesh, welded wire mesh or curved iron plate as necessary.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention, as shown in the drawings, the front of the bottom of the frame (2) of the rockfall prevention measures (1) in front of the blocking plate (3) in front of the upper and lower corners of each of the brackets (4) by welding attached, blocking The four corners on both sides of the plate 3 have a feature in which the ruler 5 caught by the bracket 4 is rotatably installed.

The bracket 4 attached to the frame 2 has a ruler catching portion 41 formed at the front thereof, and a support portion 42 supporting the rear surface of the blocking plate 3 is formed at the rear portion thereof. (5) is inserted into the through hole (7) in the fixing bracket (6) welded to the four corners on both sides of the blocking plate (3) so that it can rotate in place and move forward and backward of the through hole (7). .

The tip of the ruler 5 has an L-shaped bent portion 51, and the bent portion 51 rotates on the ruler engaging portion 41 of the bracket 4 welded to the frame 2. It can be ruled and solved, and the rear end of the hexagonal or square head 52 is formed so that it can be easily rotated using a spanner or various tools.

In addition, the inside of the ruler catching portion 41 of the bracket 4, the ruler catching jaw 43 is formed horizontally so that the bent portion 51 of the ruler 5 is inside the ruler catching portion 41. Settled in the horizontal state in the inserted state, and the bracket (4) welded to the lower part of the frame (2) is settled in the lower end of the blocking plate (3) horizontally below the support portion 42 of the rear The jaw 44 is formed so that the blocking plate 3 is settled.

In addition, as shown in the drawing, the blocking plate 3 has a horizontal bar 31 and a vertical bar 32 forming a lattice frame 33, and a ridge mesh or welded inside the frame 33 is formed. It is produced by fixing or welding the wire mesh 34, it may be attached to the frame 33 by bending the iron plate instead of the net.

The present invention configured as described above is installed in the lower portion of the rockfall prevention barrier as shown in Figs. Similarly, by turning the ruler 5 and pulling it outwards a predetermined length inwardly, the entire blocking plate 3 is prevented from falling down due to being separated from the locking portion 41 of the bracket 4 welded to the frame 2. After separating from 1), it is possible to remove the rock or soil accumulated on the back of the blocking plate (3).

In addition, after removing the rockfall or earth and sand from the back of the rockfall prevention measure 1, the ruler 5 is rotated by placing the blocking plate 3 on the separated position of the rockfall prevention measure 1 as opposed to the dismantling described above. 5) is caught by the engaging portion 41 of the bracket 4 welded to the frame 2, so that the recombination is completed.

As described above, in the present invention, in installing a detachable blocking plate at the bottom of the rockfall prevention barrier, the structural strength of the rockfall prevention measure is stably stabilized by avoiding the method of weakening the structural strength of the barrier by drilling a fastening hole in the previous frame. The bracket attached to the frame can secure the strength of the frame to some extent, and the separation and reassembly of the blocking plate can be easily and quickly performed by rotating the ruler that is rotatably installed at the four corners of the blocking plate. It has an effect that can be made.
